v1.2.3 From 288e6eaa06877ea925d8dcdac5e56310fa6d8c7c Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 2 Feb 2016 13:53:23 -0600 Subject: gpio: Include linux/gpio.h instead of asm/gpio.h Most arches have an asm/gpio.h that merely includes linux/gpio.h. The others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected, linux/gpio.h includes asm/gpio.h. Therefore, code should include linux/gpio.h instead of including asm/gpio.h directly. Remove includes of asm/gpio.h, adding an include of linux/gpio.h when necessary. This is a follow-on to 7563bbf89d06 ("gpiolib/arches: Centralise bolierplate asm/gpio.h").
